BWH, I am close to you, just down in Windsor. I had a bad Water Primrose issue the second year my pond was filled but NO FA. I killed all the primrose and the following year, my FA positively exploded! I have row crops and cattle in my watershed that I can do little to stop, similar to your lagoons. I have planted pickerel weed, arrow root and allowed the primrose to come back some and the FA is definitely more controlled. I also use some dye to help with cutting down the visibility. It all helps. The floating islands you mentioned should help, for me, I have found that I would rather have just about anything than FA as far as vegetation. Good luck! People on here can offer a lot of different ways to help you tackle your problem based on your wants for the pond. I wouldn't give up on the aeration systems, they take a while to help with the muck and have other benefits too. Happy Thanksgiving! CMM
